I have the worst luck with pillows! They never keep their shape, and I hate overly fluffy pillows because I don't like my neck to bend that much in my sleep. The GhostPillow is actually perfect. It is the perfect size, not overwhelming, but enough to give support, and it never loses shape! The gel just fills back in when I get up in the mornings. Make sure to air them out for about 24 hours though, mine came with a bit of an odor. They do have a fresh scent that fades over time, but the "warehouse" odor does go away in 24 hours.
We purchased a queen GhostBed because our old Sleep Number bed just wasn't cutting it anymore. My wife woke up every morning with a very painful backache and I often woke up many times each night. First night with the GhostBed was pretty good for both of us. Second night the better half was happy as could be while I had had some issues (nothing serious). By the third night both of us were sleeping through the night and waking refreshed and ready for the new day. Something not that easy for a couple of senior citizens. Also, I can't say enough about the people at GhostBed. I had occasion to use the "CHAT" feature twice and both times they listened and did exactly what they said they would. My experience both with the product and the people at GhostBed has been top notch every step of the way.
We really like our King-size Ghostbed. I did a lot of research and my partner was dubious about going away from traditional box spring. It didn't take long (4? 5? days) before we both realized that we were sleeping better, deeper and waking up with less aches and pains than with our box-spring. I can't really tell if the "cooling gel" layer is helping since we both suffer from hot flashes and night sweats right now but it certainly isn't any worse than before. I was waking up with a numb shoulder and aching hip on our queen size Doctor's Choice. I don't wake up with those pains any longer. I also don't wake up with all the cats crowding me - hurray for a king-size bed!
